Symptoms

Consider the following scenario:

  • You have some database availability groups (DAGs) in a Microsoft Exchange Server 2010 environment.

  • You create a management role assignment in the environment.

  • You assign management roles to a role assignee.

  • You define the scope of the role assignment to a member mailbox server in a DAG.

  • The role assignee tries to make some changes to another DAG that is outside the scope of the management role group by using one of the following cmdlets:

    • New-DatabaseAvailabilityGroup

    • Set-DatabaseAvailabilityGroup

    • Remove-DatabaseAvailabilityGroup

    • Stop-DatabaseAvailabilityGroup

    • Start-DatabaseAvailabilityGroup

In this scenario, the role assignee can unexpectedly change the DAG successfully.

Cause

This issue occurs because there is no Role Based Access Control (RBAC) scope validation when Exchange Server 2010 runs *-DatabaseAvailabilityGroup cmdlets.

2785908 Description of Update Rollup 5 version 2 for Exchange Server 2010 Service Pack 2
